摘要：
A square Helmholtz coil has been designed and fabricated using commercial grade HTS BSCCO tape with double pancake configuration. The present work is aimed at generating uniform magnetic field with a square Helmholtz coil pair useful in laboratory applications. It has an advantages over the circular Helmholtz coil which had been fabricated and validated by us earlier in terms of field uniformity. This coil is intended to be used as a background field/magnet for circular Helmholtz coil and possible characterization of High T c tapes. Design parameters details, magnetic field generated and the fabrication techniques of this square Helmholtz coil have been described in this paper. Measured current voltage (I-V) characteristics following 1.0 mu V/cm criteria and magnetic field profiles of the square Helmholtz coil have been presented in this report in greater detail. From the I-V characteristics, the critical current based on self field dependent of HTS coil is found to be 84 A. The maximum magnetic field is found to be 0.05 T from the magnetic field characteristics.
